ChatGPT App Gets Codex: Manage AI Coding On-the-Go

OpenAI has added Codex access to the ChatGPT mobile app. This allows developers to monitor and manage AI coding tasks directly from their phones. The feature works through a secure relay. All files, credentials, and permissions remain on the machine where Codex is actually running. The mobile app acts as a remote control for Codex. This means users will not code fully on a phone screen. The rollout began on Thursday, May 14, and is available in preview across ChatGPT plans on iOS and Android. Codex can now send updates to the mobile app, including screenshots and test results. Developers can check progress, approve commands, and review outputs from their phone. This matters because developers can now manage coding tasks remotely, even during long builds or bug fixes.
